STEREOSCOPE AND STEREOGRAPH.

To all whom it may concern:

Be it known that I, HARRIE C. WHITE, a citizen of the United States, and resident of North Bennington, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Stereoscopes and Stereographs, of which the following .is a specification.

This invention relates to stereoscopes and to means for retaining a pack of pictures in position on the stereoscope so that the same may be seen one after the other without removing them from the holder of the stereoscope.

The invention also relates to means for keeping the pack of pictures in alinement when in use, and to means for holding the pack of pictures together when not in use so that the pictures may be kept and used in sets.

To the accol'nplishment of the above objects, and to such others as may hereinafter appear, the invention comprises a pack or set of pictures suitably secured together so that the individual pictures may be shifted or turned from the front to the back of the pack or vice versa, as desired.

The invention also comprises means for holding the pack of pictures in position on the stereoscope so that the pictures may be turned from the front to the back of the pack without getting the pictures on the front of the pack out of alinement, thereby keeping the pictures always in focus and in such a position that a pack or set of pictures can readily be seen one after the other without removing the eyes from the stereoscope until the pack or set of pictures have all been seen.

In the drawings: Figure 1 represents a perspective view of a stereoscope provided with a pack of pictures in position for use. Fig. 2 is a detail perspective View of the pack holder. Fig. 3 is a detail sectional view of the pack and holder. Fig. 4 is a detail view of a portion of the pack.

Referring to the drawings, A designates the hood of the stereoscope, B the edge of the lens-frame, O the septum, D the handle, and E the shaft, all of which may be constructed in any desired manner.

Upon the shaft E is adjustably mounted my improved pack holder which, in the present instance, comprises a body member F provided with a recess G in which the shaft E is inserted, the body member being held in position on the shaft by means of the Specification of Letters Patent.

Serial No. 484,859.

spring clips H which are operated to adjust the holder to any desired position along the shaft E to focus the pictures held by the holder.

To each end of the body member are secured the uprights J which in the present instance, consist of single pieces of metal bent so as to form a recess K into which the opposite edges of the last picture or cover of the pack can be inserted for holding the pack in position. The uprights are also provided with projecting portions or guide members L which help to retain the pictures of the pack in alinement and facilitate the pictures being turned from the front tothe back of the pack.

In the present instance the pack consists of a plurality of pictures or cards M upon which are mounted a plurality of stereoscopic pictures, the same being held together at their upper corners by means of the rings N which pass through the elongated slots 0 which are approximately of the same width as the ring but are made sufliciently long so that the rings will not act to pull some of the cards out of a vertical plane when the same are set on one edge on the body member of the holder as shown in Fig. 3. The length of the slots 0 depends upon the number of pictures to be held together by the rings, and also upon the diameter of the ring, it being important that the length of the slots and the diameter of the rings should be so proportioned that when the pictures are set in position on the holder, as shown in Figs. 1 and 3, they will all stand vertical as the same will all rest upon the top of the body member F, the pictures being kept in alinement by means of the projecting portions L. WVhen desired the pictures can be turned from the front to the back in a very easy manner, the projecting portions preventing the pictures of the pack from being pushed out of position by the fingers in getting hold of the picture to be turned.

To prevent the pictures of the pack getting out of alinement when the pictures on the front of the pack are turned over on the back, a curved back support P secured to the body member F is provided upon which the lower edges of the pictures may rest so that the weight of the turned pictures will not fall upon the rings N so as to pull the pictures on the front of the pack out of alinement. The curved back support also permits of the stereoscope being held slightly downward without the turned pictures pulling the pictures on the front of the pack out of alinement as the bottom of the turned pictures will always rest upon the curved back support P. p

A curved front support Q, secured to the body member F is also provided which-in the present instance is made integral with the curved back member P, for the purpose of preventing the pictures of the pack from slipping off the front edge of the body member and getting the pictures of the pack out of alinement. The curved front and back support also permit of a certain freedom of movement in handling the stereoscope without getting the pictures of the pack out of position so that the same can readily be adjusted by simply tipping the stereoscope to return the pictures of the pack to their correct position.

'hile the invention has been described with particular reference to the details of construction it is not to be considered as limited thereto as many changes may be made and still fall within the scope of the following claims.

What I claim is 1. A stereoscope comprising in combination a holder, uprights secured to said holder at opposite ends thereof for removably holding a connected pack of pictures, and a curved support on said holder extending beyond the sides of said pack for k eeping the pictures of the pack in alinement and focus.

2. A stereoscope comprising in combination a holder, means secured to said holder for removably holding a connected pack of pictures, said means being arranged to e11- gage the edges of the pictures of the pack,

and means secured to said holder for keeping the pictures of the pack in alinement and focus. 7

3. A stereoscope comprising in combinameans for keeping pictures of a pack in alinement and focus, and a picture pack comprising a plurality of pictures, and means for holding said pictures together, said picture pack being removably and adjustably mounted upon said holding device.

(3. The combination with a stereoscope apicture pack holding device, comprising means for keeping pictures of a pack in alinement and focus, and a picture pack comprising a plurality of pictures provided with elongated holes, and rings engaging said elongated holes for holding said pictures together, said picture pack being removably and adjustably mounted upon said holding device.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
